Specification of Letters Patent.

Patented Nov?, 1921.

v Application lfiled. April 5, 1920. Serial No. 371,477.

a device that is easily portable, easily ap-I plied to standing posts, convenient to use 4and cheap to manufacture. I `accomplish this object, and other desirable results that will hereinafter appear, by means. of the construction illustrated in the `accompanying drawing, which is a part of this application for Letters Patent, like charactersof reference indicatingv like parts throughout the several views thereof, and in which:-

Figure 1 is an elevationk of a post with my device mounted thereon. o

Fig. 2 is a plan view of the subject matter of Fig. 1. j

Fig. 3 is a perspective view `of a portion of one of the impregnatingmembers.

.Fig 11 is a member.

Fig. 5 is an elevation of the subject matter of Fig. 4. 'o f n..

vFig. 6 is a perspective' view of a suitable tool for removing the puncturing member after the use thereof;

plan view of the puncturing In general my device consists of a pluralf ity of box like members open upon one side, the open sides of said members being curved to a radius, thus making each of said membersan arc @fa cylinder, means to clamp said members upon the periphery of a round post, packing means between each of saidy members and the post, and means to inject into each of said members a liquid preservative under pressure and to remove said liquid therefrom after the same has remained a suiiicienttime therein.

Each ofthe box like impregnating members is formed with sides 7 and ends 8, a

back 9 connecting said sides and ends, thereby forming a boX like structure open upon one side thereof, said back and said ends being curved, as shownin Figs. 2 and 3, thereb causing the member to form a portion o the surface of a cylinder. `The inner surface of each of said sides 7 and said ends 8 is channeled, and a packing medium 10 of any suitable material is placed within said` channel, the surface of said packing medium kprojecting` beyond the surface of said sidesl and ends, as shown in Figs. 2 'and 3. Thus,

when the device is'in place upon a post, the

packing medium 10 contacts with said post,

and as the impregnating members are drawn tightly upon the post, said packing medium securely separates the space within said members from the outside thereof, so that any liquid injected within said members under pressure will remain therein. Two or more of said members may be mounted yupon a post, said members being conveniently joined by suitable hinges 11, as shown in Figs. 1 and 2.

To secure said y impregnating members upon the post I provide a. suitablewinch consisting of a member having feet 12v adapted for4 vcontacting' with the post, a body 13 joining said feet, arms 14C upon said body, a shaft 15 rotatably mounted within said arms, and a barrel 16 secured to said shaft between said arms, as shown in Figs.

1 and 2.

A plurality of arms 17 areprovided, preferablyintegral with thebody 13 and one of the legs 12, and suitable flexible tension members, preferably chains 18v are secured respectively to said arms 17 said chains being passed from said arms around the outside of the impregnatmg members, thence to the barrel 16 to which they are secured.

Suitable hooks 19 are provided upon thekr outside of the backs 9 of the impregnating members for supporting the respective chains 18 while the device is beingmounted upon the post.

A lever 20 is secured to the top of the i shaft 15 which may conveniently be squared to receive said lever, as shown in Figs. 1 and 2, for the purpose of rotating the barrel 16 to tighten the chains 18. To hold the chains in tightened condition I provide a notched j bar 21 pivoted to one of the legs 12 and a bar 22 mounted in an orifice in the shaft 15k and adapted to coact with said notched bar 21 to prevent rotation of said shaft when said `bar 22 is engaging one of the notches in the notched bar 21, yas shown in Fig. 1.

To inject liquid preservative into the impregnating members l provide each thereof with a pipe 23, said. pipes being connected by a flexible pipel member, conveniently a hose 2e. J ust outside the hose connections to said pipes 23 l provide in each ofvsa'id pipes a valve 25. One of saidpipes with its respective valve is connected by a hose 26 tov a pressure pump supplying the liquid preservative underV pressure, Vand the other of said pipes with its respective valve is connected by a hose 27 toa vacuuinpump.

In operating my device,'after the` same has `been secured upon the post, the valve 25 adjacentthe hose connection 2"? is closed, and

the valve 25 adjacent the hoseconnection 26 Y is opened7 thus closing the exit from the iinpregnating members and opening them to the entrance ofthe liquid preservative under,

pressure from the pressure pump. After a sumcient time has` elapsed for the thorough impregnation of the post with the liquid preservative, the valve 25 adjacent the hose con- K nection 26 is closed, and the valve 24 adjacent the hose connection 2? is opened, thus vallowing the excess liquid preservative remaining within the iinpregnating members to berevmoved therefromby the vacuum pump. .After such removal vof the excess preservative, the 'chains 18 are slacked and the entire device rotated around the post until the im- `pregnating members occupy new positions, wheieupon the chains are again tightened andthe preservativeV injectedinto the impregnating members. Thus by repeated operations the entire periphery of the post may ,be treated with preserative under pressure.

l\[ydeviceumay conveniently be applied to standing posts by simply digging the earth fromV around the post, as shown in Fig. 1, and placing the device in the excavation thus 40 made.

To assist and hasten the process of impregnation I provide a plurality of curved plates 28 having upon theY convex surface thereof a plurality of sharpened'pegs 29, said plates being joined together by suitable yhinges 80, and havingupon the convex surfaces thereof hooks 31 similar to the hooks 19 upon the impregnating members, for supporting the chains 18 when mounting the plates 28 upon the post. These plates 28 are mounted upon the post byvmeansof the winch above described in .connection with the impregnating members, and then as the chains 18 are tightcned the sharpened pegs 29 are forced Vinto the surface of the post, thus providing indentations therein into which the liquid prevservative will' be forced .upon application thereof by means of the impregnating menibers above described. f

` To remove the plates 28 fromthe post I provide a'conveniently shaped lever consist- 4ing ofa handle 32 and a curved portion 33,

l shown in detail in Fig. 6. ln use this curved f portion `33 is placed between the upper edge v of'itheplates 28 and the post and the handle vapplication for Letters Patent all mechanical equivalentsfand substitutes that may fairly be considered to come within the scope andpurview of my invention as defined in the appended claims. l.
